[PlanetCCRMA] MAudio - the same wav in Windows and Linux sound different

[mArukqs]

More research: I found that on samplerates 88200 and 96000 M-Audio plays
correctly (tested via xmms, 44100Hz wav was used). but on samplerates
44100 to hear the similar higher frequencies I need to turn on this
deemphasis stuff, cause else recording sounds too bright.

Does deemphasis mean some sort of hardware dithering?
